L. KATZENSTEIN. PACKING.

No 105,462. Patented July 19, 1870.

LEOPOLD KATZENSTEIN, OF NEW YORK, N. Y.

Letters Patent N0.105.462, dated July 19, 1870,

IMPROVEMENT IN PACKING.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, Lnoronn Kerznxs'ram, of

the city of New York, in the county and State of New York, have invented a new and improved Steam- Packiug for Piston-Rods, &c'.; andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to r make and use the same, reference being hadto the accompanying drawing, forming part of this specification.

My invention relates to packing.foi'piston-rods, and consists in certain improvements thereon, which will be first described in connection with other parts ,ncccssary to the clear understanding thereofl' and then clearlypointed out in the claim.

Figure 1 is a vertical section, and Figures 2 and 3, respectively, views of the tops of d the. elastic plate, and the top and bottom packingplates.

A represents the packing-box, and

B, the piston-rod.

D is the central packing-piece, formed conieally, or with two opposite inclined annular faces.

E E are two plates, which fit respectively over the upper and lower faces of'D.

O O are plates, which fit over the exterior faces of plates E E, but are flat on top.

F is the spring or elastic plate, which rests upon the'packing plates, and receives direct pressure.

The latter plate is cutobliquely, to admit of its more ready expansion, while the shape of the incision renders it impossible that the lips formed can evenbe drawn out of contact.

The plates 0 E are cut, and, preferably, in two places upon opposite sides, so that they will be more uniformly moved outwardly, as they are pressed over the conical faces of the central ring D.

This double conical ring is also cut in like manner with-(1 and E, except that a slight shaving may be taken off one or both of the incised faces of the lips, to enable the ring to close arounil the piston more thoroughly.

The mode of operation is as follows:

The vertical pressure upon the fiat spring F-causes it to expand laterally toward both the c'ase and the piston-rod, and the power brought to bear upon the plates 0 E tends to force. them outwardly, as if forced over a tapering mandrel, while the ring 1), being pressed externally'on both its inclined faces, will be compelled to hug the pistou rod closely.

The, several plates may be so arranged in the ease as to break joint.

It will be perceived that, in fig. 1 of drawing, the piston-rod is broken away opposite to-the rings in order to expose the diagonal lines, which representcuts in the rings. 7

Having thus described my invention,

\Vhat I claim as new, and desire to protect by Letters Patent, is-

The spring F, packing-plates O E, and central ring D, all cut, shaped, and adj nsted together, substantially as and for the purpose specified.
